T at whom it may concern.-

Be it known that I, SAMUEL GUTH, a citizen of the United States, residing in the county of Jasper and State of Indiana, have invented a new and useful Device forUnloading Grain from Wagons, of which the following is a specification.

This invention relates to that class of devices employed for unloading grain from wagons in which a platform is employed to receive the loaded wagon and adapted to be tilted, together with the wagon, to unload the contents of the latter into an elevating apparatus.

The invention consists in the construction, combination, and arrangement of parts, as hereinafter shown and described and specifically pointed out in the claims.

In the drawings illustrative of the invention,Figure 1 is a plan view, and Fig.2 is aside elevation,of the apparatus complete. Fig. 3 is a transverse section, enlarged, on the line a a of Fig. 1. Fig. 4 is a longitudinal section on the line b b of Fig. 1. Fig. 5 is an enlarged detail perspective view of the adj ustable elevator-supporting bracket detached.

In the drawings illustrative of the invention, 1 represents a platform or body mounted upon carrier-trucks 2 3, the truck 3.preferably pivotally arranged and adapted to be provided with a removable tongue 3 to enable the platform and its attachments to be transported from place to place to adapt the apparatus to be conveyed to the location where the load is to be dumped. At each end of the platform are arranged inclined runways 4t 5, connected by hinged joints 6 7 to the platform, so that they can be folded upon the platform when not in use, and when the apparatus is being transported the runways affording means for enabling the wagon to be driven upon and removed from the platform.

8 is the tilting table, upon which the wagon will rest and will be provided with any suitable means, such as chocks, to retain the wagon in place while being unloaded. The table 8 is pivotally connected at one end to the platform 1, as at 9.

10 is a transverse shaft suitably supported in bearings 11 upon the lower side of the platform 1 and carrying two cams 12 13, adapted to engage the table 8 when the shaft is revolved to elevate or tilt the table upon its pivotal connections 9.

14 is a short shaft journaled in suitable hearings on the platform 1 and provided with a pinion 15, engaging a gear-wheel 16 on the shaft 10, so that the latter may be revolved to actuate the cams. 12 13 by power applied to the shaft 14. The power necessary to actu ate the shaft 14 is thus reduced by employing the small pinion 15, engaging the larger gear 16, so thata manually-operated crank 17 will be sufficient to actuate the tilting mechanism. A ratchet 18 and pawl 19 will be arranged in connection with the shaft let to hold the cams and the table supported thereby at any desired point of elevation for obvious reasons.

20 is a transverse shaft mounted in snitable bearings 21 beneath the rear or discharge end of the apparatus and extended at one end and forming the lower or drive shaft of the elevator 22, as'shown. The elevator is constructed with inlet 23, the usual endless belt of buckets, (not shown,) and outlet 25 and is provided with a swivel discharge-spout 26, by which the grain may be conducted to any desired point of discharge laterally. The upper or feed side of the elevator-casing will be provided with a hinged door 22, by which access may be had to the elevator-belt, if required. Means for regulating the tension of the belt are shown at the discharge end of the elevator, consisting of plates 27, in which the ends of the journal 28 of the upper end of the elevator-belt are mounted, the plates slidably mounted in keepers 29 on the sides of the elevator-casing and adapted to be adjusted by screws 30 and nuts 31, as shown.

Attached to one of the faces of the elevator-casing is a supporting-arm 32, the arm being connected byits upper end to the elevator by a hinged joint 33 and with its lower end connected removably and adjustably to the platform 1, so that the elevator may be supported in its upright position when in operation or lowered, as shown by dotted lines in Fig. 2, when not in use or when the apparatus is to be transported from place to place or when it is to be carried through contracted passage-ways, such as the doors of granaries or barns or the sheds connected with elevators or storage-warehouses. This ability to lower the elevator when required is a very important one and adds greatly tothe efficiency of the apparatus, as it provides for the use of the apparatus in localities which are inaccessible to the ordinary dumping apparatus or warehouses, access to which is obtainable only through contracted doorways. With my device, however, by lowering the elevator the apparatus can be driven through any aperture through which any ordinary vehicle can pass and the elevator again elevated when theinterior is reached and the load discharged in the manner provided for in the apparatus. Thus in barns and warehouses the grain-storage bins are accessible only from inside the barns, and in such localities the dumping apparatus can be employed only when means are provided whereby the apparatus can be conducted into proper position with relation to the receiving-bins. This perfect adaptability of the apparatus to the peculiar conditions and location and surroundings of the receiving-bins is therefore an important feature and advantage of my improvement and is novel, so far as I am aware.

It will be noted that the elevator is arranged to be raised and lowered in lines parallel to the sides of the platform 1, so that the transverse width of the apparatus is not increased by the adjustment of the elevator upon its drive-shaft, so that the apparatus will pass through a comparatively narrow opening whether the elevator iselevated or depressed.

Any suitable means may be employed for securing the support 32 to the platform 1; but a slot 34 and clamp-bolt 35, as shown, will fully meet all the requirements and is a very simple and eficient means for accomplishing the desired results. By means of this clamp-bolt 35 working in the slot 34 the support 32 may be adjusted to any desired extent to set and hold the elevator at any desired point of elevation.

36 is a short shaft longitudinally mounted by standards 37 upon the platform 1 at its discharge end and carrying a pulley or wheel 38 in alinement with a similar pulley or wheel on the shaft 20, whereby the shaft 36 may be driven by a quarter-turn belt 39, as shown. Mounted pivotally upon the shaft 36 is a frame 40, carrying a conveyer-belt 41 and adapted to receive the grain as it is discharged from the wagon and convey it into the inlet 23 of the elevator 22. This small transverse conveyer will extend across the platform 1 for a distance equal to the width of the wagon upon the tilt-table and may be tilted upward upon its drive-shaft 36 to remove it out of the way of the wagon and horses when they are being driven upon and removed from the platform and table.

42 is the shaft by which the power is applied to the moving parts of the apparatus and is mounted by bearings 43 upon the platform 1 and is provided with a pulley or wheel 44,

connected by belt 45 to a similar pulley or wheel 46 upon the main drive shaft 20, whereby the motion of the shaft 42 may be transmitted to the shaft 20 and thence to all the elevators and the conveyer, as before described. Any suitable power may be employed to actuate the shaft 42-either horses, steam, or other power.

By this arrangement a very compact and simple apparatus is produced, which may be easily and readily adapted to any locality where such devices are required and may also be readily adapted for use in localities where other devices for the same purpose cannot be employed.

Vhat I claim as new is-* 1. In a grain dump and elevator, aplat form onto which a wagon may be driven and dumped, a conveyer disposed transversely of the said platform above the same, a shaft 36 forming the pivot and the power element of said conveyer, and whereby the latter may .be raised or lowered at its free end, said shaft 36 being suitably mounted, atransverse power-shaft 20, bearings therefor, an elevator pivoted on said shaft 20, on one side of said platform, whereby said elevator is adapted to be swung vertically in a plane parallel to one side of the platform, the latter being the driving-shaft for the movable-carrier element of said elevator, and power-conveying connections between said shafts 20, 30, substantially as described.

2. In a machine of the class described an elevating apparatus, a platform, a tilting table pivotally mounted within said platform and adapted to support the wagon to be unloaded, an elevator pivotally connected to said platform, and adapted to receive the contents of said wagon and be raised and lowered by its free upper end, a supportingbar pivotally connected by one end to said elevator and adjustably connected by its other end to said platform, whereby said elevator may be raised or lowered and supported at any inclination, to enable the apparatus to be moved into otherwise inaccessible localities, substantially as shown and described.

3. In a machine of the class described, a platform for supporting the wagon to be unloaded, an elevator pivotally connected at one end to said platform, a supporting-bar pivotally connected by one end to said elevator, and having a longitudinal slot, and a clamp bolt connected into said platform through said slot, whereby said elevator may be supported at any point of elevation, with relation to said platform, substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
